Ok so I have a couple of small gaps around the purfling where i routed the channel poorly, what should I fill these with? dyed epoxy? or dyed glue? any advice would be appreciated !
thanks

Hey thanks for the reply.. do u sand immediatly/?

If the gap is too large, maybe a little sliver from the off cut board could do the job.

This does all depend on how big/small the gap is. Really if the gap is bigger than 1/32-1/16" it will be noticed no matter how you fill it.

Most of the advise I've read, and what I would do if the gap were to big is route off the binding and purfling and redo the channel, making a different purfling scheme if needed.

Sorry for this advise, but you may never be satisfied with the guitar if you choose to fill the gap instead of making it right. I know this can be hard advise to hear, but it's your guitar and only you really know how you want it to turn out. That is the dilemma sometimes. If this is your first guitar and you feel like it won't be an issue for you, use Hesh's advise and fill that gap, or if you just know in your gut that you will always look at it and say "I wish I would have fixed it" than re-route and fix it.

Either way, you will have learned another great lesson in luthier.

Same procedure (glue and sanding) if the gap is at the top?

Stephen, if the crack is on the top, I'd go with a sliver of spruce or whatever material the top is made of... It the crack is in an area where the grain starts running against it, like the top or bottom, take a shaving (with a plane) in the same area of the off-cut scrap piece and take this shaving in the same direction. This way, the grain will match perfectly. I use HHG for this.

The only wood that I found that hides gap fills perfectly, are very dark woods. Any light wood, especially spruces, show filling. It's like wetting end-grain. It shows up darker, always.

Now that being said, I've never tried the titebond method. Maybe the titebond doesn't 'wet' the sawdust as much...

I always fill with dust and just flow in thin superglue if the gap is small and on a dark wood. If it is on the top you really have to put in a patch of matching spruce like Alain said. You can mix up some dust that is lighter that the back and side wood by adding some spruce dust to the back and side dust and it should match better without going too dark. It works for me but only on small gaps. Good luck,

On darkwood like EIR, i used CA glue and EIR dust with great results, i scraped it flush afterwords.
